USCG Exam PracticeRunning fix from a single object
A navigator has only one charted object visible and cannot obtain a simultaneous two-object fix. After taking a first bearing and running a timed distance on a steady course, the navigator takes a second bearing on the same object. The advanced first LOP and the second LOP intersect to produce which type of position?
- A. An estimated position
- B. A three-bearing fix
- ✓ A running fixCorrect
- D. A dead-reckoning position
Why C is correct
Bowditch Ch. 7 §708 describes this exact procedure — bearing, timed run, second bearing, advance of the first LOP — as producing a running fix. An estimated position requires applying a current vector to a DR position, which is a different procedure.
